Not All Degrees are Equal

The Georgetown University Center on Education and the Workforce (cew.georgetown.edu) tracks the return on investment (ROI) of college and specific college degrees. Though going to college is better than not, assuming the individual graduates on time and from a good school, what you study also affects earnings.

What we know about college and income:

Obtaining a four-year degree is worth about $1 million over a lifetime compared to not earning a college degree.

Obtaining a degree from one of the 20 most elite universities is several times more valuable than earning a degree from a non-elite undergraduate university.

Obtaining a science, technology, engineering, or math degree from any respected school is better than a liberal arts degree, by an average of $3.4 million in lifetime earnings!

Obtaining a liberal arts degree from a low-ranked school is similar to not having attended a college!

The following charts are from the CEW 2015 report, based on 2014 data.

Since the median (half above, half below) household income for 2014 was $52,250, two married liberal arts graduates from a university would likely earn slightly more than the national median as a household. Two STEM graduates marrying would begin their professional lives more than 50 percent above the median!

Individually STEM, business, and healthcare graduates out-earn the national median household income by mid-career. The following chart illustrates the gap between degrees and earnings in mid-career.

Because studies in the United States and Europe suggest that "like marries like," we find that wealth increasingly concentrates with couples in the STEM and business fields. Two teachers marrying versus two technology experts marrying? That's a significant gap between those households of $60,000… a gap greater than the median household income.

People with similar education tend to work in similar places and often find each other attractive. On top of this, the economic incentive to marry your peers has increased. A woman with a graduate degree whose husband dropped out of high school in 1960 could still enjoy household income 40% above the national average; by 2005, such a couple would earn 8% below it. In 1960 a household composed of two people with graduate degrees earned 76% above the average; by 2005, they earned 119% more. Women have far more choices than before, and that is one reason why inequality will be hard to reverse.— http://www.economist.com/news/united-states/21595972-how-sexual-equality-increases-gap-between-rich-and-poor-households-sex-brains-and

The lifetime earnings gap is enormous for one person. It's massive for two highly educated people in the STEM fields.

For a technical household that's a $6.8 million lifetime earning advantage if both partners have STEM, business, or healthcare degrees. That's a lot of money, all based on what people choose to study.

In 2012, Bloomberg found that STEM degrees, and schools offering STEM degrees, offered a better ROI than other universities. This trend has held for the last three years.

Nearly a third of the top 30 schools were engineering schools, including the top three institutions: No. 1 Harvey Mudd College, No. 2 California Institute of Technology, and No. 3 Massachusetts Institute of Technology. All three schools had 30-year ROI well above $1 million, a claim only 11 schools could make. On average, engineering schools had ROIs of $603,362, more than double the ROI for liberal arts schools ($245,943), more than triple that of business schools ($141,014), and more than 26 times that of arts and design schools ($22,328).

The only schools that fared better than engineering schools were those in the Ivy League. Seven of the eight Ivies are in the top 15, and the average ROI for all eight was more than $1 million. While costs for these schools are high, several factors worked in their favor, including generous financial aid and excellent graduation rates—both in terms of how many students ultimately graduate and how long it takes them to do so. The weighted net cost to graduate was $84,241—less expensive than half the schools on the list, and half the cost of the most expensive.

A final thought. Duke University has identified schools that seem to correlate with lifetime earnings, as well. Averages are notoriously bad statistics (median being a better measure), but higher median earnings do align with higher average earnings.

Here are the 20 universities with the most "successful" undergraduate alumni as of 2014:

[NOTE Augusut 8, 2017: The marginal and effective U.S. Tax rates mentioned in this 2011 post have been supported by research conducted by Thomas Piketty (Paris School of Economics), Emmanuel Saez (UC Berkeley and NBER), and Gabriel Zucman (UC Berkeley and NBER). These economic researchers are well-respected by progressives. Data are data, though we differ on interpretations. "Income" vs. "Wealth" presents much of the challenge, as wealth accumulates but is not taxed in the United States. Distributional National Accounts: Methods and Estimates for the United States published July 6, 2017, includes the following table:

As the table shows, the effective tax rate for the top 1 percent peaked at 45 percent of income in 1944-45. Unfortunately, the overall revenue intake of the United States kept growing and the burden has been falling most on the bottom 50 percent. Tax increases on the middle and lower classes reduce potential economic growth since these individuals spe…

Though the contemporary Republican Party has never been libertarian enough for me or many others focused on economic issues, we at least imagined the GOP would lead a President Trump, who came into office with no governing experience and a platform that was populist and nationalist.

The GOP has failed to do much practical at all. If you, like me, at least hoped Trump would be contained by party orthodoxy, the year has been nothing but disappointment after disappointment.

Civil Rights: Hard to think of anything the GOP or Pres. Trump has proposed with which I agree, from gender issues to voting rights, the GOP is allowing Trump to lead on these subjects — in the wrong direction.

Gay marriage should never have been a national issue. Private matters are private, between consenting adults. The libertarians and social conservatives will always be in conflict on these issues.

On voting rights, I am okay with a basic national ID standard, as is being implemented for the TSA via new d…

Map of U.S. Minimum Wage laws (Photo credit: Wikipedia)
Minimum wage debates tend to overstate the estimated and real effects of any changes to the minimum wage in the Unites States. Most studies show a minor increase in a place with wages already rising has no significant effect on employment. But, there is a cost when wages rise quickly and there is an effect when wages fail to keep pace with the cost of living. The problem is that the minimum wage is not, contrary to any mythologies, the income of most adults with full-time work.

As the debates below suggest, there is a limit to what a local economy can bear in terms of wage growth. At the same time, we know that low wages also reflect jobs that can be or will be automated away in many instances. We are in a new era of creative destruction, with no real plan for the displaced workers without skills.

Allow me to provide an example of how silly on all sides the debate on wages is. Mark Perry gets the facts right in his piece on th…
